Hi all

I am very interested in purchasing the COBB Tuning 3" catback exhaust (mainly because of the smooth sound!). However, I also would like to purchase a downpipe and uppipe and install them all together. I've heard bad reviews about the COBB up and downpipes (mainly because of weight and fitment issues). I was just wondering if mixing and matching (eg Helix up and downpipes) would be okay or not with the COBB 3" catback. Any suggestions?

 

You can definitely get away with mixing and matching parts, however there may be some fitment issues where the pieces connect.

 

I was going to do a rs*r gt2 exmag catback w/ cobb down and uppipes
but yea kinda gotta hope it might fit.

 

i suppose since the cobb catback is three inches i just look for a downpipe that's three inches. i'm friends with a gearhead so when we make the install, i'm sure we'll be able to make it work.

 

also, will sound be affected by a catless downpipe? cobb catback sounds so good i wouldn't want to mess that up. however, i'm assuming i get more power with the catless correct? help a newb out ya'll

 

You should get a bit more power from a catless exhaust - I've been told it's approx. 5whp or so. Sound shouldn't be affected much as far as a change in tone, but it will be slightly louder without cat.
