Q's about running w/o mufflers

Okay, so I am turning my 96' bird into a street/strip car and I'd like to know if running with out mufflers will hurt the engine. I'm going to use 2.5" high flow cats and I dont know if the engine will get enough back pressure. I dont want to burn up the valves. I planned on going with out mufflers and having each side dump on the side of the car, somewhere between the door handle and the front of the rear tire. If you can use your imagination, i think it'd look pretty cool.

the car will be using an 02 stock explorer engine at the moment, future upgrades are planned as $$$ comes along.

Also does anyone know of any specific headers that work well with the explorer engine in the 96 bird, basically I just want to know what will fit.

Thanks!

You won't burn up the valves with the setup that you're wanting to run.

You may want to do a search on side exit exhaust.

My recommendation for headers are Kooks 3/4 length headers. Supercoupeperformance.com sells them.

watch out for ground clearance

ya, alot of people mentioned that when i was reading over some various posts. Looks like I wont be able to get the car lowered now and still be able to ride over speed bumps. I dont want to turn this into a suspension thread, but I suppose I could get super stiff springs and be okay to lower the car 1.5". I suppose you have to think, If a corvette can do it, so can I.

but corvetts have the exhaust pipes that run though the frames. they have holes in the frame to make up for ground clearance

I've seen a couple of classics with the pipe go along the outside of the door then dump out next to the rear tire, I dont know if it applies to your theory, but it still looks like there's ground clearance issues, but I suppse you could say that to any car that has such a low profile to the ground.

true like on the old stingrays. but somehow they have to rout it under the body to get it to the outside of the car. and even so u have to be lover than the door so it don;t hit and higher than the bottom of the car kinda.......so its tricky.

But goodluck with whatever you do.

same question about my 93 3.8 v6. I have magnaflow cats and glasspacks at the rear. If I remove the glasspacks and run just cats to 2 pipes out the rear will it hurt my v6?

doubtful it will hurt. may hurt the HP i heard with less backpressure the less HP u make. but with ppl like us with a V6 we tend to look more on sound than preformance.
