2.5" mandrel bent piping with stock muffler?
Would it be possible to use my stock ITR muffler with some custom bent 2.5"mandrel bent tubing? I want to maintain a sleeper look and sound without sacrificing much performance. Does the stock muffler flow enough to suit my needs? I'm currently running Skunk II stage one cams.

interesteing... anybody? I would figure you can do it, but you will still have that bottle neck were it meets the muffler.

What about 2.5" inch piping with a 2.5" baffled muffler? Would you see any gains from that. The stock muffler has a pretty big bottle neck especially for the 2.5" piping. Doesn't it neck down to 1 7/8", that would be a big change.
I am searching for a pretty quite performance exhaust too... I have to drive my car on the freeway 50 miles everyday, and the exhaust noise would get a little annoying.

I would assume you'll still be bottlenecking the system. I'd suggest an aftermarket Muffler, just look for a straight through design and an oval can. Then paint it flat black or something dull to get the OEM look. Dont forget a resonator to help keep the noise down. Of course if you get really straight through flow, it will always be louder than stock.

Go w/ 2.5" mandrel all the way back to an es (or something) painted flat black. You could even throw a stock looking tip on it.

Does it bottle neck down inside of the muffler or are you guys talking about the actual piping before it enters the muffler? I was talking about competely cutting away the stock piping and cutting a 2.5" hole in the stock muffler then just welding the piping to it.

Re: 2.5" mandrel bent piping with stock muffler? (ActiveAero)
both. the flange is bottlenecked, and the piping inside of the muffler is small too - its designed to be quiet and unobtrusive.
if you just throw 2.5" piping inside your ITR muffler, it'll prolly be pretty loud i am guessing...

Re: 2.5" mandrel bent piping with stock muffler? (Xlpshooter)
When I first got my SMSP header, I tried somethign similar to what you are thinking. I cut out the OE resonator and added a 2.5" section of piping. The note was rather raspy and got annoying. PS: I had Toda B's too.
Two weeks later I got Dave to make me a proper 2.5" exhaust. We sprayed it flat black and welded on my OE ITR tip. Mine only used a 14" resonator but with a 22" resonator it sounds pretty stock. Made a significant difference in the upper rpm band (butt-dyno). Never dynoed the OE set-up.

Re: 2.5" mandrel bent piping with stock muffler? (ActiveAero)
I'm selling a test system that I had on George Knighton's car. Below are a couple pics of the muffler. All the tubing is mandrel bent. The B pipe starts at the center tunnel hanger location. The B pipe has a 18" Magnaflow resonator and a short Walker resonator in the stock location. All the tubing was aluminized (since it was a test system) and the welds were mig (quick and cheap....again it was a test system). Nothing about the tubing is pretty but it does flow and the rear muffler looks stock. It's got a 2-3/4" tip.

how about you get the spoon 'street type' exhaust:
and paint the canister black like someone in this thread previously did.

I'm going to do the 2.5 straight pipe from the exhaust manifold to the stock muffler, Hopefully I will have this done before the expo...
I am also going to see if the shop will be able to expand the bottleneck in the stock pipe.
As for gains... ? whatever.

Re: 2.5" mandrel bent piping with stock muffler? (1.8L)
So all the 2.5" aftermarket exhausts will be significantly louder than itr stock muffler?
I'm in this dilemma as well, and I wanted to add an smsp 2.5" cat.

DC has an Integra application, they just haven't updated their website. I have the HyTech which is also twin-loop and I'm real happy with it.
edit- The muffler canister isn't just a big hollow can and welding 2.5" tubing won't do the trick. But there are tubes and chambers inside the can, I believe measured at 1.75" like mentioned before. Bottleneck for sure.

.....honestly, these days everybody and thier mama has a catback - so anything off the shelf or custom 2.5"+ is sleeper on an import. I mean, you have a freaking yellow car! lol
My last setup turned out to be quite pleasing: 2.5" mandrel bent piping, exhaust cutout, magnaflow 22" straight through resonator, and n1 turbo can. I found a recent video that I took of my car at idle, and it just warms my heart..... Man, it sounds so nice and low and deep... harley riders are green with envy! I am gonna use this same setup - maybe add another resonator to make it even more quiet. And I have the silencer for the n1 can should I require some serious silentness..... Get a quality exhaust man - or leave it stock!
