Greddy Supreme Catback

I just installed a new Greddy Supreme catback a couple weeks ago, and just noticed that it's louder out the left side than the right. There was more smoke coming from the left side on startup as well. I put my hand behind both sides, and exhaust heat is coming out from both sides.

Is this normal? Or could there be a slight restriction on the right side? Mind you, this catback is almost brand new.

 

Bump

 

I think you have answered your own question.

Hard for anyone else to posit an opinion, you are the only person who's ever seen the exhaust in question.

Maybe take it off and check it with an endoscope.

Endoscope, $7 inc. shipping

Or maybe just drive and 'forgedaboudit'


.

 

I just wasn't sure if anyone else has encountered this, and I wanted to ask. But thanks for the endoscope link. I totally forgot about those things!

 

Is there anything specific I should be looking for?

 

well considering echaust comes from one side of the motor and only divides after the cat. maybe the catback is faulty or there is something inside the right pipe. Take it off and inspect it. clearly the problem is in the catback.

Also you could email Greddy.

 

Honestly, this has become the least of my worries now. Just done a comp test with 7.0 as my lowest face. So right now, my mind has been focused on getting a plan together for when it officially fails.

 

Same thing happens with my stock exhaust, this isn't normal? I just figured things were taking the path of least resistance. That doesn't necessarily mean there's an abnormal restriction.
