i was wondering if anyone could help me out in choosing a downpipe...does anyone have any good advice or a recomendation for one?i have a nur-spec catback and im now looking for a downpipe to accompany it thanks

 

personally im going with the perrin setup. its a very nice clean setup. the pricing is okay. a little more expensive than a lot of the others but worth it. imo

 

There's a good amount of different downpipes out there.

There's the bellmouth design, divorced gate design, catted and catless downpipe.


How much are u willing to spend on the downpipe?

 

excellent point! there is a lot of research required. ive been researching for 6 months and still no purchase.

 

Most popular choices tend to be Helix, Turbo XS, Perrin and Invidia. Of course there are a lot more out there...I have the Vishnu dp and its really nice. Downpipes are generally very similar, and I have yet to see dyno charts showing a difference between the bellmouth and divorced wastegate designs.

 

What's your pricerange? I'd go with the maddad catted if I could afford it.

 

get a helix belmouth dp...

then you gotta decide if you want it catted or not. lol

 

I was torn between the cobb catted and the maddad v2 catted, I was worried that the exhaust might creep around the divider in the mad dad and not pass emissions, so I opted for the cobb catted dp.
It has solid construction, nice welds (I'm a welder, i ground into them to check for porosity then re-welded) and there were no fitment issues when installing it.
