Well, then I'll post on here.

Tips I got at a muffler shop by me, I can probably get them and ship them out if you're interested.

I think it sounds great!

do you lose low end torque?

that is what GTR says happens to people that make their own exhaust. H says that he rebaffles his exhaust.

My argument to that is how did he dyno test this product. Also dont you think that MAGNAFLOW has more money to R&D a exhaust product?

Personally i think that he is.... well it does not matter what i think.

i wish you would have done a before and after dyno.

I spent about $30 bucks. lol

My buddy did it. All he wanted was for me to fill his tank, a 12 pack and me to work a night shift for him.

As for low end Torque, I'm pretty sure it's a lot better now, I feel more of a pull when taking off.

i am jealous right now. :welcomeFP:

So I take it he has acsess to a pipe bender?

:P Sounds tits Mark... :welcomeFP:

Chris IZ the Shiznitt... :rofl:

Possibly... Why?

And thanks everyone else! ^_^

I think Jedi thinks you also got new piping, but my guess is you used the stock?

I know he used MOST of the stock piping but dident you still have to have something fabed up for the L shaped tail pipes and to conect the muffler to the long pipe?

From what I see, it's the stock pipping from the axle to the motor. I recommended Mark to stick with the 2.25" pipping anyway. :)

Yup, the stock pipping is 2.25", and you can just add onto it.

There isn't any need to bump up to 2.50" unless you have more than just an intake (IE headers, ported manifolds, ported heads, bigger throttle body and tune)

let me rephrase the question: Are the L shaped tail pipes the stock GTP/GXP tail pipes? Also the S shaped pipe that conects the muffler to the stock long pipe how did you/he make it?

does that clear up what in asking? :)

Wow, much discussion while I've been off.

All the pipes from where he cut, right before the muffler, before the bend, after that it's all custom. No GTP/GXP pipes, just him bending pipes and fitting them in and welding. :lurking:

ok thanks for clearing that up. I could when I get the money have one of the techs do it for me but we dont have a pipe bender so I was hopeing it was the stock GTP/GXP tail pipes. :lurking:

cant you jus get the GTP/GXP tailpipes?
