pro street or sportsman street? i'm running duals dumped under the car, 2.5" duals with H pipe pushin around 400 horse...which would be a better set of mufflers? i want it to be loud, but I don't want it to be obnoxious where i wouldn't be able to hold a convo....i'm going with a full cased muffler so i'm pretty positive both of them will be under the obnoxious sound level, so i guess the question is which one is louder???

 

I had the Pro Streets and they were obnoxious for sure...but they sounded BADASS at wide-open-throttle...no other muffler could compare.

 

Why Spintech? I have one for my Mufflex system but I consider it the best of two evils available the other being Flowmaster. Speaking from a perfromance point of view of course. IMHO I would look at Magnaflow or Dynomax. They are a straight through design and not all that loud.

 

Sportsman if you want to talk and you're dumping it under the car. My single 3 inch dumps under the rear seat right now with the pro shootout muffler and it's fuggin loud in the car. When it dumped at the rear bumper, it was fairly quiet inside. Here's a soundclip I did just recently with the microphone behind the car about 10 feet. Sometime this year I'll be running a dual 3 inch setup with the same muffler, maybe dumping again at the rear bumper.

 

welll i can sorta tolerate obnoxious because i pretty much went all summer with open headers because both of my headers had golf ball size holes in the collectors....i think i'm gonna go with the pro streets, those things sound fuggin amazing!!! i would hate to have it to quite..

 

That sounds absolutely AMAZING, and it's DEFINITELY a spintech. My 302 Mustang sounded frighteningly similar to that with dual 2.5" Pro Streets dumped... But youve definitely got a much wilder motor.... I just pitched a tent listening to that sound clip.

 

yea mine won't sound quite like that, i got a little bit less of a cam...276HR, but it should still be pretty lumpy....the pro streets are a little quiter than the pro shootouts were, so i think i'll be alright....i think i'm gonna go with the pro streets just because the case is so small...the guy doing my exhaust said to get the smallest case i could find and he said he'll tuck it right up there real nice and everything...so it sounds like the pro street is the way to go..talking to the guy thats doing my exhaust, he's got me so fuggin pumped to fire my car up!!!!

 

The Pro Streets have a really small case in comparison to a conventional muffler...I imagine they'd work great ina third gen. Only thing is theyre a bit on the tall side....Im not sure if they make a thinner one or not. But theyre very narrow

 

they are 4x8x12 i think....i'm positve on the 4" height...and that in thin compared to the others like flowcrapper, which have like a 5.5" case....the guy doing my exhaust said the specs for the sportsman streets would be a great choice, but i told him about the pro streets and he said thats excellent...

 

correction the pro street is 4x6x12.....but i was just about to order my mufflers online, and i found a sound comparison chart, and it looked as if the sportsman street was the louder of the two...i was under the impression the pro street was the loudest muffler they got...also this might sound like a dumb question, but how the hell do i order my mufflers??? i don't see a BUY IT NOW, or put your cart thing anywhere...do i have to call to order or what???

 

i read the articles about each muffler, the pro street said designed for the street, but had great results in the racing industry...then the sportsman street says it was designed as a race muffler, but was to quiet so they turned it into a premiere street muffler...isn't that saying the sportsman street is louder? now i'm kinda in a bind, which should I get?? I want it to be loud and still sound like a spintech.....i don't want it to be obnoxious to the point it doesn't really have a unique sound to it at all...

 

that car has no cat on it or does it?

 

no its gonna be LT headers, no cats, dual 2.5's to a x pipe, then keep going and dump through dual 2.5" mufflers right before the rear axle under rear seat pans...

 

any1? beacause i have to get whatever ones i'm getting ordered soon...and i need to know how also...

 

I too am about to go the duals route and I'm stuck between the Spintech and Hooker Aerochamber.

Doing the Hedman LT's into duals with an X pipe and dumps at the axel.

Like you I want loud but not abnoxious.

Something else I'm considering are the Edelbrock RPM series mufflers. Jegs lists there size as 3 5/8"x 7 1/8" and 15" long plus there stainless so they'll last.

At 3 5/8" thick there thinner than Spintech or Hooker which should aid in ground clearence.
I plan on cutting out the sumps in the floorpan under the back seats and removeing a couple inches of there depth and welding them back in so the mufflers will be setting pretty high but I still want the thinnest case mufflers I can find without sacraficeing performance or sound quality.

Kinda waiting to see which muffler you choose to aid in me makeing my decision.

 

I went with spintech, its hard to describe, but everyone thats heard it goes

 

I'll take the 5th on that question It is a temporary exhaust till I get a new setup.

 

i got 2 pro street 2.5"ers coming....i'll prolly get a sound clip within the next few weeks....i talked to the guy when i called a little bit, he said the sportsman streets are a little quiter than say a 40 series 2 chamber, and he said the pro streets are considerably louder than the 2 chamber 40's...so i'm pretty excited to hear this one

 

i know its a old thread but how will the pro shoot out sound with cats on a 305? And how quite are the pro streets compared to the pro shoot out?

 

the pro streets are a decendant of the pro shootout...i believe the pro streets are a bit quiter than the pro shootouts...but the pro streets are single in/out mufflers...how are ya thinking your gonna run some of them with cats? I think it'll sound alright...i mean everybody will tell ya 90 percent of your exhaust note comes from your motor, so you can't expect much out of a 305...

 

im thinking of doing a single exhaust dumped with cats and a pro street or pro shoot out muffler.

 

oh i see...just have a single oulet out back, then run a 3" dynomax intermediate pipe and overaxle pipe and run a single 3" pro street...that would be nice....i don't think they make the pro shootout any more...i think the pro street took its place, correct me if i'm wrong....

 

Here's an mp3 of my old 305 using the same muffler I have now (pro shootout) Edelbrock shorties, cat, 3 inch single dumping at the rear bumper.

 

that sounds nice...is that 305 stock? that sounds lumpy/mean.....i can't wait till i get mine started...dual 2.5's with pro streets, H pipe, dumped underneath with a 375 hp 350...its gonna sound real nice I hope..

 

that sound very cool EvilCartman. How do sweet thunders compare to pro shoot out?

 

klub15, the 305 had a CompCams 256H cam and I think at the time of the recording, a torker II intake and a Holley 670.

camaro86, I've never heard those mufflers so can't say.

 

are pro street loud inside the car if the exhaust is dumped? Can you still talk inside the car with the pro streets? and does pro streets sound better and louder than moroso spiral flows?

 

I had Pro Streets on my mustang, dumped, and I couldn't talk very well inside...interior noise was definitely high. But then, the whole thing was just loud. The heads contributed a lot to the volume though...

 

mine isn't fired up yet...tomorrow sounds like the day!!!! its ready!!!! so maybe i'll post on here if everything goes good...i think its gonna be pretty damn loud, but I think it'll be bearable...those spiral's dont' sound that good, and they are basically straight pipes, theres no muffler design to them...if you dont' want loud, stay away from those.....

 

And will these two mufflers pro shoot out and pro street set off alarms and will i have trouble with the cops?

 

yes they will set off alarms...it doesn't take much to set off alarms...i could set off alarms with my 96 monte carlo z34 with a 3.4 V6 straight piped with dual 3.5" exits.....i mean it doesn't take much....cop trouble, all depends on how you drive it...if you go past a cop taching at 4 grand, off coarse you are gonna get pulled over and probably written up...if you see a cop, don't be a dumb*ss...just let go of the gas and just let it coast or idle....

 

So which has more rumble and a deeper tone pro street or pro shoot out?

 

it doesn't matter..they are so close in comparisons i doubt you would tell a difference....

 

so do you think the pro street will sound loud and good with a single exhaust with cats and dumped ?

 

yes

 

have you heard about magnapacks? How do they sound? Do they sound better than pro streets?

 

heard about them..dont' know how they sound...

 

will a y pipe dumped with pro shoot muffler flow better than a magnaflow or random tech catback?

 

yes....single systems with a single in/out muffler will flow way better than a full catback with a crossflow muffler....

I don't know why your worrying about it so much, a good catback like a hooker won't restrict you till you get over like 400-450 horse....and even than it'll restrict you a couple horses...i don't know what you have for plans on your car, but pick yourself up a decent catback or something and don't worry about which flows better etc etc....because they all flow about generally the same, just some better than others...

 

thanks klumb15 you helped out a lot i already made up my mind and im going to go with a y pipe dumped with pro shoot muffler.

 

okay...hope it works out good for ya
