Hey guys, did some search but no specific topic really covered this. Just wish to know will both perform the same? Lets say i have a HKS muffler and i did custom piping how will this compare to the HKS catback or any other manufacture used? Is it just a price difference, quality or etc.... WIll the performance be equal among both? Another question is what if i was to take a catback from a car and make it custom fit on a different car? Will the performance and function still be the same if i was to replicated exactly the same as the company had offered it for that car? Lastly does the bend really matter or is it just for airflow and sound? Are you guys following? Let me know cheers

Most cat backs are Mendrell bent, where as your custom exhaust more then likely would be crush bent. If you can find a shop that can fabricate a mendrill bent cat back out of stainless steal you'ed have the same thing.. most exhaust shops use regular steal that can rust, and they usely crush bend their pipes.... Crush bent pipes don't have the same flow as mendrell bent ones, also a sound difference..

 

So I have a catback exhaust that is mendrell bent the only thing i have to do is make it shorter. Can the shop just cut it shorter and reweld back the pipes? Let me know

yea they can cut and weld a flang on to connect to your cat.

 

Will that have any effect on performance?

 

not really

 

ok i got a ? will a fastback catback fit on a coupe or r the bends diff??

 

^^^they're the same

 

^^^^x2^^^ what a hikack lol...hey Shri222...when you get the new front end???

 

put it on last week

 

then when u call for a catback for an s13 why do they ask fast back or coupe??

 

I don't know, there some differnt parts for the coupe and fast back, maybe their system is setup that way so it only can pull up the right parts... The exhaust is the same though . there is no differnece of the undercarage of the S13s

 

ok thanx

 

Yo I just got my Blitz universal exhaust put on with piping from a exhaust shop. It's a lot faster at the low end, it screams to 100 pretty quickly now. It also go's through the rpm's quicker. It's also loud as sh_t though! I'm thinking 'bout getting a silencer. I'm getting use to it slowly.

 

For all you people in SoCal in Los Angeles know any good muffler shop. I got one that i always go to but wish to get others input. Cheers
