So here is that plan, let me know what you think. I currently have a zzp header and DP with stock catback and a magnaflow muffle. (too raspy/tinny). I'm plannign on buying a hahn 3" catback with 2.5" bolt-up end. The pan is to run this first for a while and possible up grade to a 3"DP which hahn's catback allows for because i can just swap the 2.5" end for a 3". What do you guys think?

 

How would you swap the 2.5" end for a 3" ? Cut/weld? Also, make sure your ZZP downpipe is, infact, 2.5". I thought mine was 2.5" but turns out it's a 3" with a 2.5" exit for my Magnaflow exhaust.

 

Hahn has a feature where all you have to do is swap a little portion at the end to a larger exit. the exit on my d/p is bolted to my stock catback so it has to be 2.5" what do you think sound will be like ?

 

dude the hahn is a excellent quality piece, but if you thought your magnaflow is raspy the hahn is just deeper but imo its still raspy if your catless

 

nope I have a high flow cat in my zzp downpipe. Do you think it would sounds good?

Any opnions?

 

save your money and get a custom magnaflow with a big muffler.... i have the hahn, but i suguest you pm stevenflint and ask him about his exhaust.

 

what is his screen name and why?

 

That is his screen name

 

search and didn't find it

 

He had the name a little off

haha okay... so what do you think of this exhaust set up

 

I would just wait till you get a 3" downpipe if you are going that route. It's best to keep it all one size imo so you aren't "bottlenecking" anything. Plus its a pain to keep switching different sized flanges. Other people may have other opinions though. The CTI 3" catback would be nice as well.

 

yeh well I was hoping to run the 3" Hahn and then swap to a 3" dp a little later in the summer
