CUT OUT

[916Topherv6]

ok instead of spending a lot of money on a new exhaust, a friend suggested i put a cut out on. i have flow masters now, so anywho i put a cut out on the camaro today, and damn it sounds great, im glad i went this way love the sound, just thought id share that. i do have a question will running just the cut out have any negative affects on my car?

No back pressure from an exhaust will cause some problems. One of the things pretty much no exhaust causes is your valves to warp thus making your fuel mileage decrease and your power to decrease. I would only run the cut out when you race or want to show off, replace the nuts on the cut out with wing nuts to make it easier to replace and remove.

mine came with wing nuts. i love mine too and also only run will running at the track. so, i havent really used it yet.

Yea gotta watch out for that no backpressure thing since manifolds don't cause backpressure and tons of turbo cars run open downpipes non stop :rolleyes:

I have a cut out before my cat. No problems use it mainly at the track but for awhile had it open all the time. With the cutout after your cat you still have tons of backpressure, I'm assume you put yours after the cat like everyone else does.

I want 2 know the same thing. Also, is it better 2 place the cut-out infront or behind the cat-converter? I thought it was supposed 2 add power like a lot of it too! How much power does it add? Any 1 have an electric cut-out?

before the cat is good for performance and after for sound in my opinion. before will throw a code cause it will not let all the air go threw it obviously and so the cat will appear clogged or whatever. as for power, not much but it does help

As for the pre cat cut out throwing a light. Only if you drive it long enough for the computer to update itself. I drove it for 60 miles last night and no SES.

thanks for the heads up on that, i bought a twin pack of cutouts, so i have an extra if someone wants to buy it, its Flowtech, 2.5" ill sell it for 35-40 also u can buy the electric part seperatly from QTP for like 140 so basically u save money this way. let me know if anyone is interested

[img]graemlins/rofl.gif[/img] did u read this b4 u posted, why would u run cut out at track if it decreases ur power [img]graemlins/slap.gif[/img]

Well he meant the warping of the valves would decrease horsepower. Except he is full of crap. Btw cut out open I gained almost a 1mph lol

Edit: I have no muffler so the cutout only gets rid of my cat

Well the bad thing about the cutout is it increases my traction problems as well.

So some1 list the pros and cons for the cut out with it being before the cat, then some1 answer the pros and cons of using the cut-out after the cat. Please!

Before:
Pro: More power
Con: Illegal
Loud as hell

After: IMO worthless, but its better then going through the muffler and it will still pass inspection in most states.
