might do that iv seen the flap in my old muffler i might just take the mig welder hold the flap open and shoot some weld into the hing to hold it open.. other then that cuttn the muffler open and puttn it back together isnt all that fun with no help..

 

Here's an easier way:

looks easy.. but mig welding is just pulling a trigger ill try it if the mig doesnt work

 

I dunno how accurate you can MIG weld since you have to stick the wire feeder pretty far into the muffler. It's worth a shot I guess, but I don't think you'll be able to do a clean job.

 

This thread has a good muffler sectional view picture.

little update od of stock exaust is 2 5/8 " i have exaust pipe on order i think the guy said he could get me 2 3/4 wich should have pritty close to 2 5/8 id pipe should be here next week probably tuesday .. so i will hopefully get it by thursday and start doing the project maby friday or if i want to wait for chris blackevovii sunday ( hes gettn a new exaust put on his car on saturday and id have his stocker as a backup ) ( to measure the od of the pipe i used two straig edges put one on each side of the pipe had them as level as possable on the ground and in the same place on the exaust and measured between the two inside edges )

 

I WOULD NEVER PAY THIS MUCH FOR A DP!!!

I have the Megan Racing 3" downpipe...easily found on Ebay for around $130 shipped. It is as nice or nicer than more expensive donpipes I have seen. It will not fall apart and is made by the same company that makes Helix products. If your on a budget like me then this is a great DP. Hell even if I had the money I still would have bought this.

 

sounds good but im not doing it to the down pipe. im talkn about the mid or intermediate ( IP ) pipe its after the cat and b4 the muffler, the down pipe is after the manifold and b4 the cat. think ur looking at two differnt things.

 

Chintosaurus has informed me that 2 5/8 is too big ...he is welding forever...boo hoo.

 

Okay, I just measured my stock exhaust and it's just a little under 2.5" outside diameter. Probably about 2.45".

 

the two n 3/4 exaust pipeing i got awas about 1/8" too big.. so iduno what size pipeing.. any way. .. i took out the longer of the two resinators.. i hear no differ in sound maby a little when i down shifted... performance? ha not that i can feel..

the inside of the resonator or what ever i took off.. its straight thru.. on the inside if u hold it up to light their are little perforations but nothing really restricting the flow like i thought their might have been .. so it was basicaly a waist of 4 hours..

any way it was kinda fun if i take the second smaller resonator off thats on the bend im thinkn it would change the sound more.. i might do it a nother time when its not gettn cold out .. any questions let me know and ill try to answer them

night all

( sorry no pics no digital camera ) not really picture worthy any way. )
