Has anyone dyno tested the differences between a 2.5" Buschur Muffler Delete pipe/2.5" Buschur Downpipe combo -vs.- a 3" cat back or a 3" turboback?


I have the Muffler Delete pipe and was thinking of getting the 2.5" Downpipe and wanted to know how big (if any) the differences would be in performance.

 

With the stock turbo the 2.5" DP will always make more torgue than the 3". The 3" DP will make more upper end hp.

 

Hey, for what ever reason I cannot post a new thread, so can someone please past this for me?

How much gain do you get by changing the intercooler pipping.

Thanks!

 

That's good to know

I wonder if Buschur or anyone has done any dyno testing on the above scenerio?

 

Buschur has not done this, but tuners have seen higher torque numbers, on the dyno, when comparing the 2.75" HKS DP to a 3" DP (mated to a 3" catless back (or) cat back exhaust. I'll try to do a search and post a link if I can find this... Anyway, this is what Al (Dynoflash) has seen to be true IIRC.
