I have searched and searched on this forum and other forums and the web. but i guess its on everybodys opinion. Is there any 4" downpipe for these Evos 8's.. Also whats the best Test Pipe like a True 3" one and a True 3" downpipe which gain more HP and which really dont do anything....

any help would be appreciated...

 

A 3 inch pipe is plenty big for huge HP. I run a Helix V2 down pipe beautiful welds full 3 inch fits perfectly, and a Helix test pipe with CEL fix built in. I bought mine at GruppeS they are great service is spoton...Do yourself a favor get these 2 pieces from GruppeS today you'll thank yourself later....

 

4" is rediculous, and you wont even begin to need a 3.5" until your well into the 9's.

 

Umm im running a Ichiban 3" Downpipe, with a 3" Turbo XS Test Pipe. Its loud, and sounds Great. And Noticiable preformance, quicker spool

 

whats the site you bought it off ?? how much did u pay?

 

if your looking to get a dp and tp just get the DC sport 2 in 1 DP/TP its all one piece and fits perfect

 

I'm running the Buschur 3" TBE with bullet muffler, love the fit, finish, weight and sound.. check it out:
