I just read up on a T1R exhaust and it was and actual 2.5 catback, has anyone or does anyone use it and how are the power gains? thanks for the feedback

 

I've had my T1R for a little over a year now. The exhaust is great. Sounds, looks, and feels top knotch!

Dyno was done on the same day, with NO tuning.

Run 009 was the best of my stocks runs for that day. Runs 013 and 014 are the two best runs with the full exhaust setup installed. ONLY change was DC JDM 4-1, 2.5" resonated testpipe, and the 2.5" T1R catback. All this through the stock airfilter with 65k miles and no tuning whatsoever.

92TypeR:

After looking at the dyno curve, and assuming that you are driving a real Type R, your 164whp seems a little low for a ITR. I was under the impression a stock ITR would get something in the 170-175 whp, and 125-130ish wtq. Is there something different about your set-up, or does Washington have crap gas, etc.?

The gains after the exhaust are a really nice improvement, but stock numbers just seem a little low.

I have a slightly lower compression (9.9:1) GS-R motor that layed out 145/115 through the stock del Sol Si (SOHC) exhaust, and AEM CAI, and I was really disappointed in those numbers, but if the ITR's are really only putting down 164, then I don't feel too bad. I think my numbers still suck, though

Washington has great gas. 92 is better than most of the west.

Same dyno, same setup, different day (a few months before).

Bone stock, ITRs average at 165whp

 

Yeah, my bad, I was thinking of stock JDM ITR's; sorry.

Those are right in line with other USDM ITR's.

 

92typer,

sweet videos and nice sounding exhaust. Do you find it too loud for the streets/highway driving? I'm trying to pick out an exhaust for my new n/a setup however I'm trying to select something that is not too loud and annoying.

Also, how much did the exhaust run you?

 

Unless you're under a decent amount of load, i.e. uphill or accelerating, the exhaust is barely audable, but the deep tone is still present. At 4500rpms on the highway, you do not notice it too much. I had a tanabe racing medallion on my '92, and it was LOUD, this exhaust is not like that at all, and is very smooth, deep, and when cruising, does not make much noise at all.
