ultimate racing downpipe

[JaydiemTRAN]

Hmmm U.R. 3" catless down pipe with 2.75" J's Racing C304 SUS "70RS" Exhaust with a J's Res..I wonder how that would sound..

the hiss is normal. I had a pre-cat delete setup on my accord v6 and it sounded like an air leak

the reason i would like to keep stock exhaust is because of back pressure, I am sure u.r down pipe with stock exhaust would improve our tq numbers.

isn't 9th gen cat-back ID is bigger than 8th gen??

I already had my J's Racing C304 SUS "70RS" installed since Feb so I'm just wondering what it would sound like with the U.R. 3" Downpipe that's all.

Yea i figured so.. pretty dramatic change in piping so it's understandable.. but you described it best with the word “hiss".. almost like the beginning of a turbo about to spool.. again, only hear it during wot.

So far, so good.. I am getting used to the sound.. You can hear an air like sound coming from the engine bay when you under WOT. It's just the way it sounds, but i'm curious why it sounds like that. All the bolts are torqued appropriately. It feels so unrestricted. The most noticeable difference with the setup is mainly the torque, it's much more responsive.. =)

what is WOT mean? thanks!

wide open throttle = WOT
gas pedal to the floor

I have a question.. Do you remove the crossmember to remove the stock downpipe? thank

 

[S2KJAY]

No, the downpipe upper part slides out from the front of the cross member... but only if you remove the bottom half first.

So do you feel as though you gained 20 whp from this? race a bolt-on si and report back, lol

 

[S2KJAY]

Absolutely.. well I'm not positive on the HP side BUT the torque side for sure has had a significant gain.. loving it

Sweet man, it sounds really good! Just curious do you know if UR has plenty of these in stock or are they made on a per order basis?

Last time I checked they had one catless, 1 ceramic cat and two metal cat versions besides the one they were sending me..

Just ordered the catless downpipe and cat-back exhaust for the sedan with the second muffler. =)

I got the 4" rolled. I assume it will look like urs just a tiny bit bigger.

 

[Michael Kelley]

Also, I have access to a lift and pretty much any tool i need so hopefully my install goes smooth.

Good luck!
