Hey. As the topic stated, is a 1.75 inch exhaust system going to seriously hinder my h22a1 until I get enough to do it right?

What kind of performance loss ought I expect?

 

too small. you'll lose topend performance in the way of engine stutter and possible refusal to rev all the way to redline.

you'll get amazing low-end response tho... but after 4000rpm, you'll start choking the motor.

expect to lose 10-20hp

but it wont hurt your motor as long as you dont flog it. just be careful of detonation due to exhaust gas reversion from backpressure. i wouldnt rev her past 5000rpm if it were me.

 

No exhaust. :exnbp: c'mon, all the cool people are doing it!
