So my flex joints are pretty scraped up and I think they are leaking

Which is causing my exhaust to sound horrible.

I need to order some new flex pipes but not sure what size in length and diameter to get? Help anyone?

Also is there good and better flex pipes? If so what company should into with?

I'm going to weld them in at the exhaust shop once I get them

 

Members have pieced together all sorts of exhaust components including resonators, mufflers and and H-pipes. Results range from mediocre to excellent. You now have new joints - added stress points. Size? These are generally inner to outer diameter slip-on pieces right?

 

Hmm I didn't really get what you said lol

Basically I need to know what size felx pipes to order for my nismo stune ypipe

Thanks

 

Your leak should be VERY obvious if it's coming from the flex pipes, so be sure first.
There are radical differences in flex pipe quality.

 

Recommend me a good one please

 

i cant seem to find a flex pipe with the coils inside. any help?

i need 2.5"x 4"

 

No idea on brands, but I've seen the difference on one of Boosted Performance's kits. Perhaps you could PM him and he'd know some brands.
