anybody running this exhaust on there tpi??? how do you think it would sound and how hard to would it be to modify it to a 3rd gen anyhelp would be great thanks

 

You can buy the muffler seperately and have some custom work done.

However consider other choices than the SLP loudmouth, it is EXTREMELY overpriced for what it is. You get a better sound from the dynomax bullet muffler, and it's one third the price.

And also, This has been covered a trillion times.

 

I was thinkin of putting the loudmouth resonator on my car when I go to 3 inch. I was sold on it till I heard a clip and it sounded awful. I kinda have mixed feelings about it because I've heard ones I love and that one that sounded absolutely terrible. Plus, I have I hard time paying around a HUNDRED BUCKS for a hollow tin can. I think the bullet is the way to go, I have the 2.5" on my car right now and its loud and has great tone!

 

I had the loudmouth catback on my 305 TPI trans am. I thought it sounded excellent. In my opinion it gave it the perfect mix between tuned sound and the raw muscle sound. But I had a substantial amount of work done to that motor, headers, cam, 1.6 rockers, cold air intake, ported plenum, ignition, high stall converter are a few to mention. Many things change the way an exhaust note will sound on a motor. The SLP will sound way different if it were put on a stock 305. But overall I liked the sound enough where its going on my new GTA too!

Oh and I almost forgot, it bolted right up for the most part. I had to make a few mounts for it and massage my old Y-pipe, but I was going from a different aftermarket system to this one, not stock straight to the SLP so I can't help you there too much but I dont think the stock y-pipe is far off the location of the one I used.

 

I had it.

It sounded just gawd awful. I sold it.

 

Sounds great until you leave for work early in the morning or come home late at night, don't think my neighbors car for it when I do some tuning in the driveway either. I have a hollowed CAT so that adds to the sound level, might put in a high flow cat or bullet muffler to replace the hollow CAT to calm it own a tad.

 

I have one on my stock 305. It sounds great. Check the thread i just started on this subject in exhaust section. I finally got the muscle sound i wanted.

 

I had it on my 91z28 and it sounds like crap. it was just a LOUD obnoxius(sp) noise. I added in a dynomax bullet muffler in place of the resonotor AND a flowmaster muffler ihad lying around and it was still loud. granded my car has a lot of work to it but even with just the bullet muffler, it was LOUD. I also have no cats so if you plan on putting this on then dont get rid of your cats. you will need hearing protection in the car.
