I was thinking of just installing a Y-Pipe into my Exhaust system and keeping everything else stock JUST the Y-Pipe. I've seen some people say I would gain a LITTLE in hp but at the expense of TQ. I've heard others say I it would effect anything at the Low End and would help a bit in HP. Are there any Dynos to support either claim? What are you guys opinions through your experience and or research. I'm thinking of getting it down this weekend so please respond soon if possible. Thanks

 

I don't know - i've seen arguements going both ways w/ no real proof from either end.
