iheartjayDem

iheartjayDem

really..wow.
i really want the bc spec II

How much power are you putting out? I'm going to make an assumption and say you're only going to need a 60mm. Any bigger and you'll lose power.

Really? I thought it was 2.25". That is the exhaust that came on my car and i got a 2.25" cat on it. I went by the "exhaust purchasing guide" on team-integra which said it is 2.25".

We need more info! Mod list, and future plans. For the most part a 2.25 or 2.36 will suffice.

I'm running 3" but i dont think that 2.5" would hurt anything on your setup....

Is that OD or ID? because that makes a difference. Article on TI measures ID.

agreed...people who run the 2.5"-3" exhaust are running Turbo applications where it actually helps to have bigger piping. If your motor is fairly stock with bolt ons, 2.25" or 2.36" is perfectly fine.

But the important factor is that it is a chambered muffler that causes unwanted backpressure. The exhaust itself is mandrel bent. to Honda for mandrel bending an OEM exhaust.</TD></TR></TABLE>

you sure about that? the stock exhaust off my brother's old 96 gsr is crush bent.

My OEM 97 exhaust is mandrel. </TD></TR></TABLE>

The GSR, LS, RS, GS OEM catback systems are all crush bent. Only the OEM ITR catback system is mandrel bent piping.
