Straight Pipe

[matt23o]

1. If I replace my catalatyic converter with a straight pipe, will that do any harm to my engine or anythingelse?
2. I may buy a bolt on off of ebay so I can take it on and off when I please. Will switching back and forth from a straight pipe and a cat. converter do any harm to my computer or anything else??????
3. If anyone did this to their dsm motor, can you tell me how much louder your car is or how much improvement you think you gained if its worth it....etc

Thanks for all the help

Ive heard that the gains are not going to be as great as they will be on a turbo car, but you may notice a difference. I have also heard that if you put one on you may lose some power if your exhaust is too big, due to lost backpressure. If you have a 2.5" cat back then you should be fine and notice a bit of a gain. If you have anything larger than a 2.5" catback, then you will lose too much back pressure and lose bottom end performance. I don't think that you will encounter any problems bolting one on.

I say go for it.

i've got one. screw ebay. get it from www.testpipe.com .

i noticed a small difference & exhaust is MUCH louder. i think it's worth the low cost for a mod.
