I just ordered the top speed pro 1 exhaust and was looking at going ahead and buying the stillen y-pipe. I wasnt sure if those two mixed will have a good or bad sound. So any suggestions would b appreciated. Thanks

 

I personally would not have bought the Top Speed exhaust. I know its the more "affordable" of the Cat Backs out there, but your just asking to be called a Ricer for putting a "coffee can" exhaust on an Infiniti, I much prefer to spend the money on a more OEM looking exhaust with only polished tips and the muffler all but hidden.

 

^^ This dude

Anyways i have Topspeed exhaust and everyone loves the sound. There is no problem with running a stillen y-pipe. While your at at throw some test pipes or high flow cats in there.

 

ha..yeah i heard a lot of ppl say it sounds awesome, but yeah im lookin at titek or helix test pipes
