i just installed my megan racing test pipes today and for some reason they seem to be too close to the car and vibrate against the metal plates on the bottom of the car. has anybody else who installed these tipes had this problem? im going to buy dynamat tomorrow if thats the case but i just wanted to see if i did something wrong or if theres something else i could do to fix the problem.
My other question is that sometimes when i let off the gas, it sounds like i get a little back pressure. should i be concerned? its barely noticable but at this point i notice everything lol
BTW, i dont think anyone has done my combo of tp and exhaust (megan v2 tp and stillen true dual) so i just wanted to tell everyone it is LOUDDD. the only downside i see is that it is raspy sounding through the whole powerband when in WOT but w.e you win some you lose some. The pull in first and second is nice

 

ummm you can just take out the cross member brace, and you can also take out the heatshields above the cats. you shouldnt be too concerened with the back pressure. You should get some megan headers to finish your exhaust. After headers, get a tune. This will make you faster than a lot of NA g's. good luck.
Im running stillen gen2, kinetix hfc, and dc headers. I love the gains

 

thanks alot. i wont run into any problems if i take off the cross member brace? and i think the test pipes will rub even with the heat covers off. im just going to put some dynamat and heat wrap the test pipes to get rid of some of the rasp.

 

Nope u wont have any problems with the cross member brace off. Yea u can heat wrap the cats, and the y pipe as well. It will reduce some rasp
