Hideous exhaust note

[Jpqintx]

So I just added Texas Speed catted long tube headers. I already had a xpipe and Roush axel back. The sound is terrible extremely raspy! Don’t mind loud but can’t stand the raspy ness turned up to 100!
Will replacing the xpipe with a hpipe make a difference? Or should I just buy a new cat back? Some people are telling me to put resonators back on. Want to buy something today, I can’t drive this thing like this. Any help is appreciated

H pipe will help a little but will still be quite raspy. Bottle resonators after the crossover would help significantly. Vibrant 12" would be good. Two of these: https://www.amazon.com/Vibrant-1793..._rd_t=40701&psc=1&refRID=WC9FKVVC4CTRD1TTHDNR

MagnaFlo Tru x or equivalent is your best bet. My old combo(TSP, Steeda X, SLP LM II's) is similar to yours except I have TSP catless longtubes. I put the Tru X on and changed to FRPP/Borla axleback. Perfect sound with the longtubes now. Not as loud, deep musclery sound!

Replace that X with a resonated X.

Just ordered the Magnaflow Tru-X

Check out this thread, its based on an 18' but same principle:

I just got done with my 4th exhaust set up and I am finally somewhat pleased. Here is the short version:

-If your still 2.5"...... the Magnaflow 12468 will pretty much kill the rasp. Some have used 2.5 to 3.0" adapters to make this work as well. Unfortunately they don't make this resonator in 3".

-If your 3" and keen to stay 3" bottle resonators as mentioned are the only way to go. They won't however reduce the rasp completely, more like 50% if I had to put a number on it. For me it took these and a muffler swap to get the sound manageable. I still wouldn't mind it being a tad quieter but its the best I can do while staying 3".

If I just waited 7 min! lol

Good choice!

you will be very happy with the exhaust after install. No rasp, no drone, pure tone.

Long tubes plus an X pipe plus Roush mufflers, yeah that's about as obnoxious as it gets. The resonated X pipe will help a lot.

Exactly where I am going when I get long tubes. I can stand the open X and Roush right now, but I know I am going to need a proper resonator with headers.

I have TSP LTH, steeda x pipe and OEM active exhaust axle back.. It sounds amazing to me over 6k.. under its raspy as f..... even on quiet mode.. i knew going in.. as every single video with a LTH and xpipe showed, but its a lot.. I was going to swap a hpipe, already ordered to see if i liked it better or that Tru-x Magnaflow if the hpipe doesnt get me where i want to be.. 6-8k i love.. anything under is awful lol

Seems to be a common problem on our platform!

Lol dang too bad you didn’t see my threads. I have almost the exact same set up minus I had the H vs the X. There is still a ton of rasp with the magna X I actually just took mine off because I didn’t like it. I found that using two of the 12” resonators instead of the manga flow x is where I wanted to be. The manga x quiets it down way too much and creates an insane amount of rasp.

Get the longest resonated tip you can fit. That will be your quick fix.

I couldn't disagree more, and I had it paired with one of the more raspy axlebacks (Corsa Sport, the Xtreme mufflers). No rasp at all, but I do agree that it quieted it down and neutered tone of the exhaust too much. Agreed that two inline resonators with a regular X is where it's at.
