Has anyone ever used or heard any feedback about their exhaust kits.

I found them on Ebay and their kit is priced very good.

 

got one----great fit and great product!!!

how hard was it to get the down pipe to fit on? Much bashing of the firewall? did you notice a performance gain?

 

I got my exhuast from Warpspeed and am very happy with it. Check out their website, they have other options that might be a little cheaper than whats on ebay. I think the only one is the system with the glasspack muffler, otherwise ebay is pretty cheap. Their feedback is 100%, and for the number of feedback received is pretty darn good if you ask me.
They have a great product, and awesome service. They provide you with more than enough pipe, I think I still have a pipe sitting in the shop (4'+ long) that I didn't use, guessing it's the muffler delete pipe. Everything lined up well, except for one hanger. I had a few questions and called them, and they were more than nice and willing to help in anyway. Got everything hung in place and tack welded everything together and is solid as can be. Installation is pretty easy, but it always is better to have an extra pair of hands to help. I did mine by myself and it just took time, especially with the downpipe.
I am very happy with it and think they are worth a serious lookin' at for buying. They are a regular performance exhaust shop, just not someone trying to sell exhaust to make a quick buck.

 

I ordered a exhaust for my brothers cummins. Very good place to work with and really good product.

 

What kind of power/fuel mileage increases did you see?

 

you will only get a performance increase if you do the intake also.
the biggest reason for the larger exaust is to lower egt's, you will get quicker spool up but it wont add horsepower. mileage will increase 1-2 mpg. i have a warpspeed system for sale, was only on truck for a couple months. did some other mods and 5" was needed. i was really happy with it, just wasnt enough with the other mods i did.

 

I am looking for a new exhaust, what truck did your'se come off of? SD or osb? Why are you taking it off?


Are you over 450rwhp? If not why do you think the 4in. wasn't big enough? A good 4in. system will support a good 400rwhp and that is hard to get out of a stroker!
