X-Cellerator or Markski's exhaust?
 

I need to go with a new full 3 inch exhuast to enable my car to reach her full capabilities.

I am torn betwwen the Speedtech X=cellerator and Marks' exhaust.

Both seem to have excellent flow (my #1 concern) and quality. I am getting a great deal on both as well.

Both have a great sound, although I am leaning towards the sound of the Speedtech.

I have a friend who bought marks system w/o cats and the sound is awesome !
Never heard the speedtech but i truly believe that is sound good to and of course is a good exhaust :)

Gonna sound crazy here but maybe dyno both and see which one does better;) maybe both parties would agree? I know it's early morning;)

Unpossible Alex!!!!

I also like the BBI...a Lot, but I can't swing the price right now.

Sean have you ever thought about just getting straight pipes put on for the days when we go out racing. I mean anyone can install the straight pipes for you in about 30-45min. You are going to have more power with your size turbos with straight pipes.

Personally I run a Switzer setup, but honestly if you want the most power straight pipes is going to be the way to go. I don't know why anyone would want to run a muffler setup when on a large turbo a straight pipe is the best performing. It may not FEEL like it, because of the loss of back pressure, but peak HP numbers will blow a muffler out of the water.

I thought about thgis, Chris. I would run straight pipes during the Supra Nats, for example and my EP the rest of the year.

However, here in Houston I get regular chances for action all the time and w/ out warning so really I want the extra power on a regular basis.

honestly how could you even compare the two ?markskis is made in house , by hand to your specs !!!need i say more ?

as far as the sound again.... no comparison. but do as you wish. just dont want to you be banging your head against the wall afterwards....

OK then....how about Mark's verses BBI's?

BBI's system is awesome !!!! does everything great . marks sounds and the bbi sound very VERY alike, and its cheaper.

I like the the muffler area is reinforced on the BBI but as mentioned, the price difference is substantial.

Markski all the way !!

Another vote for the crazy Polack.

They're both great units. I'm leaning towards the 76 Speedtech X beacuse of the OEM tip utilization.
