Default Best Turbo Exhaust

whats everyone think? i might be getting a GSR with an 18G greddy turbo kit on 7-8psi. hes running a Mugen twin loop right now and i dont think thats a 3in so i was thinking it could be restricting a little flow

im new to FI - thanks guys

Thermal? N1? HKS?

thermal is very nice but i have kteller 3inch. the thermal is actually crush bent but they are clean bends. i like the kteller exhaust better because of the cleaner mandrel bends. then you can either go with a magnaflow style muffler like the thermal, or you cant beat the sound of a 3 inch N1 muffler on a turbo car.

How do you figure the Thermal is crush bent? From the pics, it looks like manderal bends.

Exactly. All bends on my exhaust are constant diameter and not crush bent.

Copied and pasted from TR&D website:

TURBO SYSTEMS
Thermal Research & Development features a line of exhaust systems designed for the Turbocharged Acura and Honda. These systems are made of 3" mandrel bent stainless steel pipe and require some slight modifications to your high-flow catalytic converter. We include an extra 3" flange for an easy installation of the exhaust system. These systems are a true 3" and will not connect to a stock catalytic converter.

Even a mandrel bend can have some slight imperfections.

Do you think they'd really put up false info on their site?

You can also find plenty of video clips of a thermal 3" system on my teggy, just click the link in my sig, and scroll to the bottom of the page, there's a bunch of media clips I put in there, in case you want to hear what it would sound like.

DAX...we must be thinking on the same wavelength..lol...

That's because you didn't have a Thermal you had a OBX 3inch exhaust or something that look like a Thermal

some of you please take the time to look at the thermal. i had a thermal about one year ago and it wasnt obx. i got it and saw that it was even on a crush bent machine because there were marks on the exhaust. im not here to trash thermal at all because the exhaust is great and its made great.

Mandrel bent piping has to be put on a machine and there are occasionally marks left behind when doing this as well. All I know is that I closely inspected my exhaust when I got it before I installed it and it was all mandrel bent. I would say the welds could look a little better, but outside that, great piece.

yea, all bending machines leave marks. My 45* bend for my downpipe has a few "wrinkles" because a certain amount of material cannot be taken up during a bend

I've got the Kteller 3" with a magnaflow muffler...I've also got a dynamax 3" muffler where the resonator would be. It's not too awful loud. Sometimes it gets a little annoying while cruising on the E way...but It's liveable.

I'm 3" DP, no cat, directly to 3" Thermal exhaust. It's actually quieter than when I was NA with a Tseudo Fireball catback, cat, and HP header.
