which is louder?

[kh15]

OK for the cat-back section of my tbe exhaust project i have narrowed it down to the borla hush or the spt performance exhaust. which one do you think is louder and if so how much?

[shamrock]

Good question, I would get Borla. its suprising that Borla does not make a vety loud exhaust like helix or HKS. I wish they did

[JiveMasterT]

The SPT is louder.

I have the Hush, very nice sound, very deep, not too loud but definately loud enough to hear a difference from stock. I haven't had my radio on much lately, just been enjoying the sound of the exhaust. The SPT is louder, but some say it gives an annoying drone on the highway.

Borla does make a louder exhaust, its a single tip design, they also make another catback, the XR-1 which is a little bit louder yet.

The cat back is a walk in the park. The down pipe is a little trickier if you are doing that too.

someone told me you have to pull the tmic to do the down pipe

Yes you do, it's in the way.

I didn't remove my TMIC when I did the DP. Everyone always complains about the heatshield being so hard to get off... I thought it came off relatively easy, the whole install was pretty smooth actually.

The catback can be done in a 1/2 hour, it's literally 2 bolts, slide the old exhaust off the hangers, put the new exhaust on the hangers, and bolt the 2 bolts back in. Done.

sorry to dig up this old thread but i figured i would use this rather than creating a new one but anyway, i just ordered the borla hush cbe and i was wonder honestly how much whp should i be expecting to gain from this cat back?

[Herknav]

from just the Hush?

Probably very little...

[WReXd]

Catbacks don't do much unless they are coupled with a downpipe. The stock downpipe is MUCh more restrictive than the stock catback.

I am leader of the cult that says catback not worth the $$ if we are talking power gains...
