i did a few months of listening to clips and research before doing my exhaust

LTs, H pipe with dynomax high flows, 2.5" pipeing, force pro series (flowmaster) mufflers

it passed emissions, was loud when it was WOT, but at idle would not **** off the neighbors, and doesnt sound ricey

^^ my favorite setup with just the exhaust done (basically).

^ that setup sounded good, would have liked to hear a WOT rev tho. i like my setup for the sound down low, i fool new people every week at the meets i go to, think my car is a v8. but with the dumps it resonates the interior a lot

MAKE SURE to plug in the front o2 sensors while the LT's have yet to be tightened down. I just installed mine last weekend (Thanks to Shaunmac). I tried to plug the o2 extension after the install and I got my hand stuck... numerous times. I have yet to do a catback so the car is still just sitting, but I also used a BBK H-pipe with highflow cats. It's also best to go about reinstalling the EGR after the headers are torqued down cuz it's a pain to get that copper tubing to bend. the BBK H-pipe also has bungs for the rear o2 Sensors which I will be utilizing. Also, the gains from the LT's themselves will be much more noticeable with a tune (I use 93 Octane)

I'm thinking about leaving 2 stock cats on for a while... that going to negate my gains from the LTs?

Shaunmac9128

negate? no. restrict? yes. You can get a set of high flows for under $200.

Glad to hear you got them installed man, post up a video when you get everything all finished up.

Haven't gotten them installed yet. They were shipped yesterday, hoping to get them installed sometime before next friday. I think I'll keep 2 stock cats on for now, then switch over to high flows when I have some more cash laying around.

WoahPony

how are you gonna use the 2 stock cats? are you gonna chop and reweld them in the new system?

And yeah, as soon as I get the ccatback installed I'll post up a few clips. As of right now though, it is 1: LOUD as HELL on the road (so loud I can't hear my 10" JL subs) and 2: running like POO and I'm guessing it's because none of the o2 sensors are plugged in and there's 0 back pressure from the mufflers. So chances are the stangs gonna sit for the winter and I'm just gonna zoom zoom around in my mazda

so the long tube headers have o2 sensors and so does the mac h pipe we only have two o2 sensors which o2 bungs do i use the one on the h pipe or the one on the headers ???

Fink

both... buut keep the 02 sensors seperate/remember which position they came from.
