Stock catback with just catless front pipe - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Keenercarguy · 04-08-2016, 09:07 PM

Has anyone run the stock exhaust but just thrown a catless front pipe in? I'm in the market for a used ISR (formerly ISIS) performance street catback right now (I posted in the WTB section), but I was considering going with a catless frontpipe in the meantime if the sound is improved. (I'd be transitioning back to a highflow cat later when I change headers, so the catless frontpipe will be only temporary)

It's still going to be pretty quiet, I ran like this for a while. You get a bit more tone out of it. Though I might have a different stock cat back. Not sure if they changed the whole thing or just tips.

If you're planning on getting a catted front pipe later, then you might as well get one now. It would be pointless (and a waste of money) to get at catless just to change again. Also the sound wouldn't do much.

I'd be buying used and then probably just selling for the same price later so the money is a none issue.

Depends on the front pipe.

Fujitsubo is identical to stock in terms of sound.
Berk catted front pipe is louder than stock by 3db, even with the stock catback exhaust.

Others will be somewhere in between...

Very good to know! Thanks! I was looking at the ISR and Invidia options.

I'd go with catalytic converter - LESS header. It'll get you more gain + better sound. I have Borla unequal header with Invidia Q300 cat-back. You can control the loudness to your favor. I love this setup.

Definitely not the borla though, Gruppe-S(Tomei white box) is much much better quality for cheaper.

haha yea, I was one of the first batches from Borla. It's not the best, but so far holding good for me!

Yeah I totally intend to go for a header eventually, but I kinda have my heart set on the Nameless 4-2-1 header and don't really want to spend money on anything less. I'm going to wait until I start co-op'ing as an engineering student and then get a header and go flex-fuel at the same time. Basically I want to change something up for cheap right now because I just really feel the need to get under the car again.

weederr33 · 04-09-2016, 09:48 AM

I have the Nameless 4-2-1 EL header (it's not catted btw), and it is awesome! It also looks beautiful, too.
