Straight piped stock exhaust...

[Scooter_092196]

For anyone looking to straight pipe their factory 3 1/2" exhaust, I found a supplier for the straight pipe to match the offset muffler that many of our rigs have. I'll let everyone know how it goes.

Kinda pricy but when I'm all said and done, I'll have a straight piped exhaust w/ 4" stainless tip for well less than $175 w/ my lb7 cat delete pipe, muff delete pipe and the tip and it won't be all hacked up.

Just to let you know RPMoutlet is not the most reputable place. Ive heard quite a few complaints about them.

Thanks for the heads up. I paid thru paypal so if they fork me around, I'll recover my $$ thru paypal and let them fight with RPM.

On my LLY I had a muffler shop weld in a pipe for my muffler and cat for $50

x2 for my LBZ.. we did a Cat delete, and Muffler delete for $50.. Then I dropped the cash for a 4" straight from MBRP..

I ordered one for my truck, cut the exhaust and went to put it on and it didnt fit worth a shit. So I then proceeded to order a complete MBRP system and was very happy with it.

I built my own out of left over 3" stainless schedule 40 pipe. Overkill for this but it was free. the diameter is about the same at 3.5". I used two forty fives and fabbed up my own offset then welded it on to the existing exhaust. I did the same thing to delete the cat. About six months after that I was given the remnants of a 4" exhaust including new front pipe that I use to make my current stack setup. That piece seems a little pricey but if it will bolt right in it might be worth it. I know I had a lot more time than money in mine but I also have all the tools available to me.

i bought 30" 3.5" flex and a 90* 3.5" elbow chopped up the old tail pipe and did a side exit on mine less then 100 bucks

I've checked around here with about 10 different exhaust shops and nobody has the iniative to work with the factory exhaust. I figure I should be able to make this one work, even with minimal finnagling....

Got the pipe. As stated above, it was a about 5-6" too long. I had the exhaust shop cut it down and it still slipped over the stock exhaust. He had to fill a little bit when welding, but it's on there and sounds t!ts!!!! I just wish I would have done this sooner.

I'm glad to hear that worked out well for you
