Spoke to my father-in-law this past weekend about resurrecting our project to put true dual exhaust on my Tek. I am so excited to see and hear how this turns out!

Other mods in the making.

1) Reupholster the seats
2) Add a blue carbon fiber dash
3) Hella Fog lamps on the brush guard
4) Nerf Bars
5) (Still working out this one) The wife wants flames put on the Tek. Maybe blue or silver flames

With my recent pay cut (economy sucks) my mods have been put on the back burner but I'm slowing getting around to them all. I hope to have a couple more mods done before the rally this year  Tongue

Greg
Just a caution on the exhaust,
most smaller C.I.D engines actually perform better with a little back pressure in the ehaust >>>. by opening up the flow, you can actually reduce the torque [very important for towing] output of the engine [even though it sound better]

A dual exhaut is appreciated in the GM orange tek with the superchager as the more air flow you can get in the quicker you need to get it out >>>> which overall increases performance >>>> but in  a stock engine, it may do more harm than good [ and also create warrantee issues]

I would do some research before you invest
However, to each his own :rolleyes:

Just my .02

I know what your saying.... However my father-in-law owns a muffler shop and builds custom street rods. He says that it can be done without any loss to performance and when he's done it will sound mean  :angry:  as hell!   Cheesy

Too bad we can't do that here in NC... It is against emission laws to have "True" duals on a catalyst equipped vehicle... There has to be a cross pipe to tie the duals together. Sad

Of course... I have never considered duals on anything other than a V8...

I understand that you want the H pipe (a cross pipe connecting both sides for the engine exaust) configuration becuse the engine requires the back pressure.  This is what I heard.  A dual exaust would be nice just to help with flow.  Hopefully you see a improvement Greg F.

P.S.  Take some pictures of how you routed the pipes.  I will be doing this mod when I need to replace my exaust.  Thanks!!  :lol:

Yes... that's it! an H pipe! Smiley

Ya know... Greg, your father-in-law could make show bar brush guards for us with his pipe bender!!! (As long as nobody wants a chrome one...)

I had a buddy that owned a muffler shop and let me play with the pipe bender. I ordered some stock and made a brush guard/light bar for my Pontiac 6000 (Don't ask)... The bracketing system was sloppy, but hey! I didn't have a great deal of experience with that stuff (and you couldn't see it anyway Wink )

But I think she bought it like that didn't she? Also wasn't it just a split off of the main pipe?

I can't remeber....

I know some of the addon's she has , she bought that way, but I thought she said she added the exh
could be my mistake?

If you are going to do a tru duel exh
You will need to run 2 cat cons
probably not enough room under there?

The best option would be a performance Muff with 2 tail pipes, this would give you the best back pressure and keep down the typical import raspyness
