I have a 91 rs 305 tbi. My exhaust was all screwed up so I cut it right behind the cat. My question is can I run a straight pipe from there with no muffler? Will i lose power? I wanted to get tubing and run it out right before the back tire with no muffler is that ok, any suggestions? thanks....

 

you wont lose power, but it will be loud, and it wont sound good, it will just be loud. Might get you a ticket as well.

 

On my old 92 RS, 305 TBI...I cut the pipe just after it went over the axle, then ran it straight back from there. Stock manifolds, no muffler, just the cat.

Never failed inspection & never even got pulled over for excessive noise.

I guess that says something about how weak a stock 305 TBI really is!

 

Horsepower makes noise........noise doesnt make Horsepower

 

If your low on cash then yes run a straight pipe, what everyone on this forum seems to forget is not everyone can afford a 355 or 383, the little 305 will be good enough for some V8 sound.

 

hey now....i own a bolt on LG4 305....i ran a straight y-pipe for 2 days. The god awful sound was too much to handle lol..

hell i got an old video of my lg4 part car LAWLS
