Looking for good sound not annoying. Do you know anyone other than TTI that makes a kit to connect to stock manifolds? -C

on my 71RR, I ran headers,21/2 pipe and SuperTraps.. sounded great, no probs
as said 21/2 is plenty for a 383..
I am truckless..

I say find a local gearhead exhaust shop and have them bend up a 2.5 system. No reason to donate $$$$$ to TTI when you can get a full custom system made local. You are in MI, shouldn't be hard to find a guy.
I want my fair share

Thats a bad idea. You will save money, well... you MAY save money, but it WILL be slower and less efficient. The local guy, like pretty much every other local guy with a press bender will likely make a mess out ov things and charge you for gold. A 2 1/2" pipe on some ov the more extreme kinks will be bent down to close to 2" in some parts... which means you'll be essentially running a 2" to 2 1/4" system... which is way too small for a 383.
Press bends are obsolete... out with the $12 glasspacks and sheetmetal header flanges. Mandrel systems are getting pretty cheap... cheaper than local shops press-bend systems most ov the time.
To the original poster - the quality should be comparable across the board, cost is something you'll have to shop around for, and sound... sounds is something YOU have to decide. Its a personal thing. If you need to hear the different mufflers, spend an hour on YouTube and you can find pretty much any combo ov car, engine size, muffler, etc. I like Spintech or Borla. Magnaflow flow very well, and are quiet if you like mild, but i personally dont care for the sound. Flowmasters sound good (i think) but dont flow all that well, and can be found on every second car with a license plate...

2.5" would suffice but eventually you will swap in a 451 or a 470  so might start with 3" which as said will be louder and dynomax muffs are good and additional glasspacks alongside the rear springs for resonators will quiet it more as will an X pipe system (dont know why the X pipe system works for quieter but it does). definitely mandrel bends. www.speedwaymotors.com has a nice mandrel universal 2.5" set for cheap (iirc ~$150) with swedged ends that fit together very nice. Myself I run quiet muffs with cable cutouts and by the time they hear (& realize) what I have, the money is already in the hands of a neutral third party and I'm seconds away from nailing it

I'd go TTI route over local...nobody that I know of in west michigan that I know of can mandrel bend, nearest I could find was either by detroit or chicago...compression bent 3" necks down to the same cross section as mandrel bent 2 1/4" in a 90 degree bend.
and I've been dissappointed with local exhaust shops in the past, and they aren't cheap either...my last full exhaust, with me supplying the flowmaster Y, header flanges, and dynomax 17769 muffler (big single) was over $275, with ugly compression bends and sloppy welding (after I specifically told them NOT to weld the aluminized pipe), where the welds rusted out in 3 years...

Had a local (at the time) shop in Auburn, WA do up a custom 3" system on my '01 Durango R/T. Ceramic-coated headers to a Y-pipe through a 3" cat to a Magnaflow muff and out the back. All in the factory location, using factory hangers, and all mandrel-bent. Real nice work. Stan's Headers in Auburn, WA, FWIW. All welded together. But, it was NOT CHEAP. All tolled, I could have purchased TWO TTI setups for my RR with what I spent.
The 3" TTI on the RR was not cheap either, but I was able to put it together myself on the car in the garage, and it fit perfect. No hassles. I'd do TTI again with no hesitation.

I'd much rather pay TTI for the absolute best pipes in the country and install it myself. What ever extra it cost I'm gonna save by not taking my car to someone's shop and have them and there customers lean all over it and have them test drive it, NO THANKS.
I have had TTI for over 10 years now on my 340 car and they sound great, everyone looks and gives me the thumbs up!
My 440 car has 3" TTI on it and I kinda wish I would have gone 2.5 so it would be quiter but it runs great. Dynomax super turbos on both cars and like I said, EVERYONE asks about the exhaust. It has been the best money I ever spent on exhaust and one system is 11 years old. Drove the hell out of it this weekend.

MY VOTE is 2 1/4 ...material is cheaper PLUS you could have it done in SS that way ... for almost the cost of regular 2 1/2.

- 2 1/2" is way more than enough; I wouldn't consider 3" unless I had well over 500hp - I agree with the TTI stuff being worth the $$$. Fit perfect, thick flanges, nice mandrel bends.....put it in myself in an afternoon - I like the Dynamax Ultraflows; they are very low restriction, don't drone and sound nice IMO.  Dave
