I have 1999 trans am. Ls1 has the following mods. 96mm intake manifold with a ported snout to fit a 102mm throttle body. 104mm air lid with k and n filter. Sd tuned so maf is delete has 4 inch coupler from lid to throttle body. 1 7/8 headers, full 3 inch exhaust with a Flowmaster. Now I know everyone hates flowmaster and says you lose power. So I was wondering if I put a single cutout after the y pipe but before the muffler would I see a power gain

I was only going to use it on, dyno, track or racing. not the whole time. How much gain do you think?

Said EVERYONE who rides with it open full time

True story! Get a electric cutout that's remote controlled

Love my QTP...... I usually ride with it about 1/4 open. Get a little rumble with my dual/dual that way. Cruise night and shows..... Wide open!!!!

Yeah so it can rattle apart every couple hundred miles.

I have had mine for 3 years with zero issues. Mine is from Raceland and it's very well built

That's a really good price! So it fit good as well?

98CayenneT/A

Too bad they don't have a 4" version. Might be tempted to try it.

All I ever had was issues from my QTP 4".

Ya I know what you're talking about with the electric cutout rattle but I have not ran into that issue with the one from race land.

FWIW I gained 5hp across the board with a 3" cutout open on the dyno vs closed through a full magnaflow catback. I had a summit brand cutout and it broke 2 times in less than a year so I took it out.

98CayenneT/A

At the track I always run with it open now but when I was messing around a few years ago at the track I generally ran a tenth faster with it open.
Give the race land one a try if ya want another one

I might get another one eventually. I cut it out of my exhaust completely for a "cat" for emissions lol

Next time I go to the track I might just take my catback off and just run it with the y pipe open since it's essentially the same thing.
