Didn't T1R show larger gains on N/A with the 70mm exhaust? If I recall correctly they did. That would be 2.75" not quite 3 and not too much bigger then 2.5". I know that bigger is not always better but for the f20c's case I think 2.75" works. Besides, going up 1/4 inch only holds another 50 cubic inches...I don't think it will hurt performance.

Anyway, I started this thread to find out peoples opinions who are running this or something like this on an N/A car. If there are none, I am willing to be a guinea pig...so thats ok to. I don't want to go 3" but thats what I was told, by Greg, that it was what Spugen makes. Can a 2.75" (70mm) variety be made? Thats really what I want.

Also if anybody with a 70mm T1R is reading this, or Amuse R1000, or J's 70RR...what is your impression on that...did you ever run a 63mm exhaust before it (besides stock of course).

 

After R&D of the T1R 70R, the placement and size of a resonator plays a big difference, the difference in placement means either a gain in HP, or a loss in HP.

 

sorry to hijack the thread, but if anyone has their silencer still and don't think they need please PM the price.

thanks

 

don't get 3inch for n/a. i had a 3inch on my hatch and there was def. loss of low end torque.

 

no I don't want 3inch I want 70mm (2.75")

 

[QUOTE=AHHVTEC,Sep 22 2005, 10:01 AM] If you are staying N/A DO NOT get the 3".

 

ya it is a 2.5" but you can get them "custom" made

 

ohh okay.

 

 

if i brought a muffler to spugen can they make me a custom straight pipe exhaust out of titantium.
