just took the cat out and put a test pipe on, just to feel the difference. felt major loss of torque, will be putting the cat back on asap. anybody have the same experience?

 

I didn't notice a loss of torque when going to a testpipe. I did go from stock cat to Carsound cat to T1R testpipe, maybe I didn't notice because I was gradually stepping down.

 

I have noticed a torque increase from adding another muffler (all motor street car)

 

Maybe you could use some cam tuning.

 

i just put the t1r testpipe in today LOVE IT

 

I doubt you felt and major torque loss by removing a restriction in the exhaust.

 

On my previous 97R, I put 5 Zigen Axle back N1 muffler and damm, the torque at low end were gone! Keeping it stock on my 00R now.

 

i think with a test pipe you have a trade off, you get improved high end response but you lose torque down low

awesome how long did it take to find that one out

 

well. i have t1r test pipe + b pipe + mugen twin loop

when i went from stock B pipe with spoon to my current setup. i didnt notice any difference in tourqe..

hell ITR's have zero toruque anyways.. who cares

 

If you felt "major torque loss" from taking your cat out, I think you broke something.

The stock cat is a restriction. Adding a test pipe will give you more power, like 2 hp or something. Put the cat back in and save some trees.

 

It's a trade off. You need some back pressure to create torque. On the other hand, you sacrifice top end power. When you eliminate the cat, you feel a torque loss but, feel the RPM going up crazy at top end.

 

lack of backpressure with test pipe will make you feel sluggish in low rpm. test pipe comes in real handy when driving at high rpm.
