yeah i should have enough money to buy a GTA trans-am by november or late december and i was taking into concideration getting the dynomax emissions leagal headers, y-pipe, highflow kat, intrmd pipe, and highflow muffler and i wanted to know if it sounds down right kick *** and if its a good upgrade for my buck anyinfo will be helpfull :lala:

 

Well I wouldn't say they sound totally kick ***. I had a super turbo on my car and it wasn't loud at all. On the other hand that is with stock manifolds, cat, and a 2 1/2 in. intermediate pipe, not a 3 inch like I should have. I think you can get an ultra flow muffler with the catbacks now and they are suppposed to be louder. Flow wise, however, I think dynomax is one of the best systems.

 

That cat-back system is only 2.5", you need 3" for that 350, I would reccomend the hooker cat-back.

 

Hello, I have a dynomax cat back on my 91 350 GTA and it is 3 inch, it has the muffler with a 3 inch inlet and 2 2 1/2 outlets on the left side. It is really quiet at idle, too quiet but at full throttle it sounds killer, i think a little higher pitch than flowmasters. My buddy said from down the street it sound like an LS1 at full throttle. Im sure the car will be louder after i finish installing the headers , car is jacked up now for that. Will probably go to a single 3 inch cat now, pulled out the whole dual cat assembly out as a unit and put it into storage. Later, Dave

 

Hooker headers and Hooker headers. Sound clip in the sig, with my old mods before cam/intake, but I have Edelbrock headers.

 

hey steve forget all that dynomax poop and get the hooker cat back and since ur keepin it emmissions legal get the dynomax headers and a hiflow cat. and plus remeber nothing screams like a hooker....cat back that is

 

haha hey tim whats up yeah thats a good *** idea i was just thinking of just keeping the whole exaust one brand if it would save money in the long run but yeah i love the way yours sounds and i dont know if dynomax makes 3 inch which is what im lookin for :lala:

 

yeah i wanna get a formula 350 TPI now i just realised they still look good but they arent as heavy so my gear to weight ratio will be hella better and still be able to get the ram air kit and functional hood for it from GTA accesories either way im psyked that i will be riding with my budies and be an 3rd gen f-body member and loyalist trust me boys once you get a GM f-bodie everything else just isnt that good :hail:

 

yup:lala:

 

i am still shopping around for my exhaust!

good luck with your choice(s)..

 

yeah im gunna do the exaust on my car my self seeing as how i work at an STS and they will let me use the tools and the shop on my off days so long as im not interfeering with any work needing to be done but other than that im gunna do the work :hail:

 

Hey I just saw in GM High Tech Performance they put a 3 inch dynomax catback on a 305 TPI formula and picked up 2 tenths and i think 1.5 mph. Just thought I'd mention that.

 

damn man i wanna get the whole dynomax system to see what it sounds like because so far none of you seem to know personaly what the "whole dynomax exaust system" sounds like so now i have an excuse to get it this way when i get it i can relay what it sounds like to all of you haha :lala: :lala: :sillylol: :rockon:

 

Make sure to get the 3" Ultra Flow kit if you go with dynomax. Super turbo mufflers sound weak to me.

 

yeah i wanna go for noticably loud because ive learned something about loud throaty v-8's and that is the louder and nicer it is the more the hotties notice you mwahaha i wanna sound orgasmic im so psyked about it i havent found anyone selling one yet but im lookin for a formula 350 preferably with t-tops with less than 100,00 miles on it and in good condition if anyone knows where i could find one near NJ you would forever be in my debt ive thought about buying an import like a supra or a 300zx but they are too expencive and just not an f-body v-8 thats all i want baby but it has to be the pontiac camaros are kick *** but i personaly think the f/b and the t/a just look beter :lala: :hail:

 

yo but seriously which headers for dynomax do i need because honestly i know nothing about the "kind" of headers i need and i want maximum flow and sound so if anyone can give the list and names of the parts i would be greatfull just to a lil guestimating on how much it will cost me

 

I would reccomend hooker hedman or slp if you want maximum flow. The dynomax only have 1.5" primaries compared to the others 1 5/8" or 1 3/4".

 

Borla...nuf said. hahaa

 

gm high tech performance just put a dynomax cat back on one of there 350 thirdgens, went from like 14.9 to 14.7 and gained like 2 mph on the trap speed
