How much of a difference would it make if I were to just do the downpipe and cat delete right now? Would it be noticeable do you think or not?

 

The difference should be there. However, It is recommended to do cat-back first before doing anything else.

 

Cal,can you still do this package with the turbo back,ralliart drop,and MR valve??Ill call tomorrow if I dont hear from you.One more thing..got any of the C/F exhaust shields for the rear bumper in stock??Thanks

 

Hello,

Yes I can work out a package deal for you. But keep in mind that the Ralliart drop in filter will take 3-4 weeks from Japan. The MR valves will be here any day now. As for the C/F exhaust shields, it is something we do not carry at this time. Lancershop.com has it for very good price. Please check with them on this item.

Thanks

Thanks,just placed my order for the turbo back.I forgot to ask about the C/F shield.Ill call tomorrow and see if you can get in my order.

 

Does anyone have any pictures from under the car witht he full Helix turboback exhaust installed?

 

i don't have the turbo back, but i do have the Helix DP & CB. heres a pix of the catback sections. (sorry don't have pics of the dp yet.)

 

Would you consider the TB to be a loud exhaust? I understand that the setup includes a test pipe and pretty much anything w/o a cat should be pretty loud, but I was just wondering if I could get some feed back on the noise level. (basically is it annoying cruising around town or on the freeway?) Thanks!

 

installed my TB today. sounds great. not near as loud as i thought it might be. i am very pleased.

 

 

W/o the cat, the exhaust noise level will soar upto 101dB which is quite loud w/ droning noise. While when I was testing with stock cat, its around -94 to -96dB with throaty sound under WOT. I am currently running the TB w/ high flow cat, the noise is tolerable at cruising speed while provides deep rumble exhaust note during WOT.

Hope this helps a little..

Thanks

IMO the tone is cool. the sound is deep (like a bass) rather than loud and irritable like some exhaust out there. anything w/o a cat is bound for loudness. when i slapped on the dp, it sounded a little deeper than before (it's got a mean grrr!), but the power is definetly there! overall a good bang and bling for the buck! Keep up the good cust service Cal!

Bump!

 

Does the Helix exhaust package hang any lower than the stock exhaust anywhere....i more or less have my car slammed and just wanted to make sure there wouldn;t be any issues there. Thanks!

 

why does it look like it tapers down in diameter just before and ater the muffler? it loks like its only 2 inches or so by the picture.
