full exhaust research....chime in
full exhaust research....chime in I need to redo my entire exhaust on my 2000 Camaro. its full aftermarket true duals.......cheap china headers, (no cats), even crappier x pipe dumped before axle out of too bullet mufflers. sound good but scrapes like crazy, and exhaust fumes in the interior. the collectors on the headers are leaking cause they were welded so cheaply.
so what setup is best for me? is there a brand of headers known for better ground clearance? my front end is lowered 1.25" on aftermarket springs and the rear is only rubber hose mod on the stock springs. catback known for good ground clearance?
the exhaust smell in the car.....it might be the leaking collectors but could also be no cats or could be the dumps before the axle. Must I have cats to avoid this problem? must I go with rear bumper exit to avoid this smell?
I had a friend put the tsp headers on this 2001 Camaro which is lowered about 1". he had to unbolt at least one motor mount to get the headers in. this has already ruled out tsp for me. anyone experience this?
anyone with aftermarket exhaust on lowered f body...please chime in and tell me how you like your setup.

Checkout the speed engineering thread about their new over the axle true duals and headers.
I have similar exhaust to yours and I’m lowered on 1.25” springs. My pacesetter LTs don’t scrape its the bad exhaust setup with bullets.

Speed engineering dumped duals are fantastic. Take your time adjusting them. Replace supplied clamp hardware with grade 8 bolts, nuts and lock washers. Clamps themselves are fine. Shouldn't back out. Turn exhaust tips 45 degrees. They make headers too. I have pacesetter armour coated headers and they work great. If you have a short Tarm then you may need the MWC double drop member.

I'm running 3" single all the way out the back like stock. Without cats and the roof open there's still exhaust smell coming in when I'm sitting at a long red light. I'm used to carbs and big blocks so it doesn't bother me. If you don't want to smell anything you should look into some high flow cats. Dumping the exhaust under the car or out the sides will just make the smell even worse.

My brother swears by Speed Engineerings 1 7/8 long tubes. He had less fitment issues with those than he had with my Texas Speed 1 3/4 LTs. I'm running the speed engineering out the back true duals. That combined with the Texas Speed LTs sounds amazing. People ask me all the time what kind of exhaust I'm running because it doesnt have that typical Y pipe/catback sound to it.

1. Get the speed engineering long tubes and true dual exhaust setup. As others have said, you will need to be careful with selection of short tunnel mounted torque arms and x members. Long torque arms present less of an issue. For short tunnel mount, both UMI and MWC offer options that will work, with UMI offering the better ground clearance. The MWC true dual x member for their tunnel mount short TA doesn't work with the SE true duals, but it will work with the TSP true duals.
Pros: all polished stainless, sounds loud and mean, very affordable
Cons: may be too loud for some tastes, fuel smell, specific x members needed for short tunnel mount TA setup
2. Get this: https://ls1tech.com/forums/generatio...e-cutouts.html
Pros: Allows you to have the best of all worlds, quiet or loud, great ground clearance on lowered cars, no fuel smell, compatible with certain short TA tunnel mount setups
Cons: Much more expensive, not all components are polished stainless
You only need a short TA if you 1/4 mile track the car. A long torque arm is a better option for a street only car and offers much more fitment compatibility with various exhaust setups.

I didn't have to remove the k-member when I installed my TSP LTs; just had to figure out the "right" angle to slide in place. I also installed SEs true duals, but I went back and installed cats for the exact same issue your having with fumes. It was terrible but all is well now that I have cats back in.
