I'm in the last half of collecting my turbo project, and It's time for me to start thinking about exhaust. I've gotten some pretty good deals on parts so I wanted to use the extra money and have a nice quality muffler.
I mean something along the lines of borla (turbo/XL), tanabe (turbo specific,concept Gblue?), apexi, greddy I don't think makes universals outside of the vehicle specific catagory...... amoung other nicely made mufflers(be it round or oval....but mostly oval.)
but I got to thinking that turbo quiets exhaust, and with most quality mufflers their tone and decible level tend to be lower and more sophisticated than say a magnaflow, dynomax or flowmaster/ amoung the other various mufflers that just get slapped on. I started to search and surprisingly didn't find much info on turbo owners and muffler brands.
I'm basically asking if this would be a very nice investment or just a bit of wasted money.
my suggestion after having quite a few different exhaust set ups on my car now, go 2.5" turbo back and get something like a Magna flow, or borla muffler and defiantly go oval ahah something about the round ones make it look SOOOO ricey...
but then i am all about having my car very quiet, nothing i hate more then a loud car...
i have done the 3" turbo back route and its just too loud because the 3" mufflers are a race style straight threw with very little to muffle sound... where as if you go to a 2.5" you get the street style with more muffling... so if your really set on a 3" system keep it all 3" and just put a muffler with a 2.5" inlet on... your not going to effect it really do this (or not that i noticed any thing any way) and if you ask me 3" on a Jbody is WAY to big unless your putting down 400+hp numbers
take a look at all the muscle cars they all run a 2.5" exhaust and are putting out any ware from 325hp-400hp ... hence 3" being over kill on a jbody...
The First Twin Charged jbody
blue car (R.I.P) - 240whp @7psi..
silver car - 305whp 315lbs.tq @15psi (91 Octane) or 420whp & 425lbs.TQ @20psi (94 octane+Alcohol Injection)
All dynos run on a Mustang dyno
def staying with the 2.5.
I basically made this post cause I wanted to get something different(no more magnaflows) with this setup. Just wanted to have that nice little something. horsepowerfreaks.com has the apexi N1's in different colors. I hope their gold is more of a bronze cause thats the scheme of the rims and car. But basically I want the quiet sophisticated type quality.
Mabye look at it like, I want a muffler made with a turbo in mind to be behind it.
2.5" exhaust, borla muffler would be a good setup if you want to keep away from magnaflow, since they are over-rated and everywhere. Like Josh said if your looking at putting out more than 400+hp go with a 3" exhaust.
