Default Help me choose an exhaust

2002 camaro ss m6

Car has American racing 1 3/4 headers with a catted y pipe magnaflow catback with an electric cutout, UMI tunnel mount torque arm, Moser 12 bolt, small cam, and lowered 1 inch.

I’ve had a SLP LM1 and it was too loud. The magnaflow is a little too quiet but the main issue is it’s made with all 2.5 inch piping so I’d like to ditch the whole system.

The exhausts I’m looking at right now are:

Texas speed over the axle true duals
Speed engineering over the axle true duals
Texas speed over the axle catback with built in cutout

Im open to other suggestions as well.

Any help is appreciated. Thank you.

I'm leaning towards the hooker blackheart true duals when the funds are available. I was stuck between all of the exhaust systems you have listed as well and decided on the hooker system because of ground clearance.

I would be adapting the exhaust to American Racing headers as well. A few guys have adapted it to longtube headers using flowmaster reducer cones. I thinks it’s pretty simple to do, but it isn’t plug and play.

My vote is for duals, so pick whichever setup you desire. I’m going to get the Speed-Eng full exhaust (1 7/8” headers and dumped duals) when I get my next LS1 project.

Corsa sounds the best of all Fbody catbacks I've heard. Mangaflow, Borland, GMMG, Hooker Blackhart, and a dozen or so others.

My favorite is the quiet but great flowing SLP Dual / Dual and cut out ideally electric for making noise.

My 99 TA 's LS1 with heads and cam, 1 3/4 LT Hooker headers, mufflex dual 3 inch 4 inch Y pipe set up plus SLP Dual / Dual sounded better than the new 416 does with 1 7/8 LT Kook's headers, custom y pile and the Hooker Blackhart. The Blackhart is quality and has great ground clearance. The Hooker Blackhart has a lot of good points, I don't think sound quality is one of them. At least it's a good x pipe set up that is fairly priced.

The Speed engineering over the axle true duals are very loud.

Last night I spent some time browsing through the Speed engineering and Texas speed true dual threads. Looks like there’s some serious ground clearance issues. I believe it was 2” for a lowered car.

blackhearts don’t bolt up to longtubes from my understanding. I don’t want to visit any more muffler shops because that’s the reason I’m buying a new system.

Has anyone heard of TSPs catback with the the built in cutout? Looks kinda sweet. I don’t know how a catback with a cutout flows in comparison to true duals.

If you decide to stay with your header and y pipe setup, check out the hooker aerochamber catback. Big fan of it for 5 years now. Not stainless, but holds up well. Respectable at idle and mean as he'll at WOT. Good luck with your choice.. My setup is mated with ARH headers and ARH catted y pipe.

For a single I pipe cat back, the Corsa sounds great. I have a Gibson and it was pretty tame with the stock cam. Now that I have a BTR stage 2 , headers and high flow cats it has some bark but still is civilized while cruising.

I ended up finding a used magnaflow 3 inch catback for cheap. The piping difference is pretty big between my muffler shop ghetto rigged 2.5 inch catback. Haha

Post a clip when u get a chance. I think magnaflows sound really good on LS1 cars. I didn't find the SEs tru duals exhaust to be that loud but my cars motor is stock.
